Locking a Motor

[ozrien]

kgzak is correct. Talon SR, Jaguar, and Victor 888s have a brake/coast jumper.
Victor SP has a button to select brake vs coast in neutral mode.
Talon SRX has a button to select brake vs coast, and can be software selected over CAN bus.

See Talon SR User's Manual for more info for original Talon and Talon SR.
See Talon SRX User's Guide for more info.
See Victor SP's Quick Start for more info.

"Brake during neutral" simply means that when 0 the motor leads are connected together. I wouldn't say it's "locked", but the generated back electromotive force will resist the rotation of the motor.
